When pollutants like dust, mold, pollen and pet dander get trapped inside
your home, it can seriously diminish your indoor air quality. Fortunately,
by choosing the right furnace filter for your heating system you can significantly
reduce airborne particles and improve the air inside your home.
--The following section provides more information about the various types
of furnace filters that are available so you can make an informed decision
about which is the right choice for your home.
Fiberglass furnace filters are effective at eliminating large particles like dust. However, they
allow smaller particles like pollen and mold spores to pass through with
ease. They are the least expensive style of filter, but they are also
the least effective at removing debris from the air. Typically these filters
are geared more toward protecting your furnace than protecting your health.
Electrostatic filters have a static charge that attracts particles from the air. They are more
effective than fiberglass filters and have the added benefit of not needing
to be replaced. Instead, you can wash and reuse them.
Pleated air filters are more effective than either fiberglass or electrostatic filters. The
pleats help increase the surface area of the filter so it can trap more
particles. These furnace filters are highly effective at removing allergens
from the air and are one of the most popular choices for homeowners.
HEPA (High Efficiency Particulate Air) filters are the most effective type of filter. Typically they are used in hospitals
and labs where clean air is essential. HEPA filters usually are not recommended
for residential use because they restrict air flow and over time can damage
your furnace. If you do choose a HEPA filter, you should hire an HVAC
expert to measure the air flow of your heating system to make sure it
is not being restricted by the filter.
